[Administration of RU 41740, a preventive anti-infective immunomodulator in an acute respiratory episode. Synthesis of 3 clinical trials].

In both adults and children RU 41740 exerts an immunomodulating effect and prevents recurrent respiratory infections. Patients with such infections frequently consult for acute episodes, and it was deemed necessary to evaluate the safety of the drug given concomitantly with antibiotic in acute infections. Three double-blind, drug versus placebo studies were conducted in fragile institutionalized or hospitalized patients. Antibiotics were administered simultaneously with RU 41740 in one group and with a placebo in another group. The studies performed by Albarede and Ollivier showed that in acute respiratory infections RU 41740 was well tolerated and resulted in a more rapid improvement of severity score. Grassi and al. studied chronic bronchitis patients admitted for acute on chronic episode. RU 41740 produced a more rapid improvement in the most severely ill patients, and it was well tolerated. It is concluded that RU 41740 can be initiated safely in acute episodes occurring in subjects with recurrent respiratory infections, and that it results in a faster improvement of clinical symptoms.

Growth and precocious puberty.

Treatment of precocious puberty of central origin is aimed at controlling the development of sexual characteristics and improving final height. Increased growth rate is one of the major clinical symptoms, accompanied by an even more marked advance in bone age. Medroxyprogesterone acetate and cyproterone acetate have provided almost satisfactory control of pubertal characteristics, but with accompanying adrenal insufficiency. The data with regard to growth and bone maturation are contradictory. LHRH analogues have recently become available, and provide good control of gonadotrophin secretion. In a series of 21 cases (13 girls, 8 boys), a significant decrease in growth rate was achieved in both sexes with an LHRH analogue, with a significant increase in the height age/bone age ratio; control of gonadal secretions was also obtained. These results are only preliminary, but provide hope that the final height of these children will be improved.

Factors influencing outcome after intestinal transplantation in children.

We evaluated 131 patients (6 months-14 years) who experienced 21 deaths before listing, 11 continuing on the waiting list, 38 well on home parenteral nutrition, 6 off parenteral nutrition and 59 transplanted (20 girls) aged 2.5 to 15 years, (18 >7 years). They received cadaveric isolated intestine (ITx, n = 31) or liver-small bowel (LITx, n = 32), including right colon (n = 43; 23 LITx) for short bowel (n = 19), enteropathy (n = 20), Hirschsprung (n = 14), or pseudo-obstruction (n = 6). Treatment included tacrolimus, steroids, azathioprine, or interleukin-2 blockers. After 6 months to 10.5 years, the patient and graft survivals were 75% and 54%. Sixteen patients (10 LITx) died within 3 months from surgery (n = 3), bacterial (n = 5) or fungal (n = 6) sepsis, or posttransplant lymphoproliferative disorder (n = 2). Rejection occurred in 27 patients, including 10 steroid-resistant episodes requiring antilymphoglobulins. The grafts were removed due to uncontrolled rejection in seven ITx recipients. Surgical complications were observed in 38 recipients (25 LSBTx) within 2 months, including bacterial (n = 22) or fungal (n = 11) sepsis, cytomegalovirus disease (n=12), adenovirus (n = 11), or posttransplant lymphoproliferative disorder (n = 12). Forty-two children (19 LSBTx) are alive. Weaning from parenteral nutrition was achieved after 42 days (median). Factors related to death or graft loss were pre-Tx surgery (P < .01), pseudo-obstruction (P < .01), age over 7 years (P < .03), fungal sepsis (P < .03), steroid resistant rejection (P < .05), hospitalized versus home patient (P < .01), and retransplantation (P < .05). Colon transplant did not affect the outcome. Interleukin-2 blockers improved isolated ITx (P < .05). Early referral and close monitoring of intestinal failure and related disorders are mandatory to achieve successful ITx.

Role of lipid emulsions in cholestasis associated with long-term parenteral nutrition in children.

BACKGROUND: In children who depend on long-term parenteral nutrition (PN), liver disease is a major complication that may lead to end-stage liver failure requiring liver transplantation. METHODS: This retrospective study investigated the influence of lipid emulsions on cholestasis onset in children receiving long-term total parenteral nutrition (TPN) with lipids. Ten children who presented with a total of 23 episodes of cholestasis, associated in 13 cases with thrombocytopenia, were studied. RESULTS: Changes in the lipid delivery preceded these complications in more than half the cases. The temporary decrease in lipid administration led to normalization of bilirubin in 17 episodes. CONCLUSIONS: These data suggest that lipid supply is one of the risk factors for PN-associated cholestasis. The link between cholestasis and the reticuloendothelial system overload needs to be better understood. Prevention of cholestasis might include the decrease in the lipid load. When cholestasis occurs, lipid supply should be temporarily stopped, especially in the case of associated thrombocytopenia.

Intestinal transplantation in children: preliminary experience in Paris.

From November 1994 to November 1998, 20 children (2.5 to 14 years) received a jejunoileal graft alone (SBTx; n = 10) or in combination with the liver (SBLTx; n = 10 and/or the right colon (5 SBTx). Indications were intractable diarrhea of infancy (n = 8), short bowel syndrome (n = 6), extensive Hirschsprung disease (n = 4), and chronic intestinal pseudoobstruction (n = 2). Immunosuppression included tacrolimus, methylprednisolone, and azathioprine. Current follow-up ranges from 6 to 54 months. Five patients died (3 SBTx) within the first 2 months. Acute liver rejection occurred in 5 patients during the first 2 months. Sixteen episodes of intestinal rejection during the first 3 months in 11 patients (8 in 4 SBTx) were successfully treated in all but 3 by increasing tacrolimus dose and/or a 3-day methyprednisolone bolus or required antilymphoglobulins in 3 cases. Surgical complications occurred 8 times after SBLTx and 3 after SBTx. Infectious complications were more frequent in SBLTx recipients. Reversible Epstein-Barr virus-related posttransplant lymphoproliferative disease occurred in 3 recipients. Five presented cytomegalovirus infection. The SB graft was removed in 5 recipients (3 chronic rejection). All patients were started with oral and/or enteral feeding from the 7th postoperative day by using either normal food or protein hydrolysate diet. Currently, 10 of 11 children (8 SBLTx) achieved digestive autonomy after 5 to 30 weeks. All recipients gained weight; however, growth velocity remained reduced during the first 6 months because of the steroid therapy. Overall graft and patient survival is higher after SBLTx. Intestinal transplantation is indicated for patients with permanent intestinal failure. However, because parenteral nutrition is generally well tolerated, even for long periods, each indication for transplantation must be weighed carefully in terms of risk and quality of life.

[Liver transplantation with a living related donor in the child].

OBJECTIVES: Liver transplantation with living related donor has been recently developed to compensate for the insufficient number of liver grafts for children. The major problem is ethical because it implies voluntary mutilation of a healthy person. This paper report results in 37 living related donors. PATIENTS: Recipients were followed in Enfants-Malades Hospital. Investigations and donor surgery were performed at the Digestive Surgery Unit of Beaujon Hospital. RESULTS: One donor was re-operated for bleeding, and another one a biliary fistula treated with percutaneous drainage for one week. The post-operative course was uneventful in the other donors, with a follow-up of between 2 and 50 months. Thirty-three children are alive (90%), one of them underwent a second transplant for arterial thrombosis. Vascular and infectious complications, and the number of rejection episodes were the same as in transplantations with a deceased donor. Biliary complications were frequent (15 patients out of 37) and significantly increased morbidity. A teenage boy who received a small graft (0.9% of his weight) presented initially with hepatic insufficiency without encephalopathy. CONCLUSION: This technique has been shown to have a good balance between benefits and risks. Our experience confirms this, especially in very young children. Each case should be discussed individually and parental consent should be obtained without external pressure. Experience with this technique should be continued and at the same time the use of cadaveric grafts should be optimized.

[Anderson's disease. Clinical and morphologic study of 7 cases].

Anderson's disease is a rare autosomic recessive condition involving the transport of fat through the intestinal mucosa, which could be due to a defect in the intestinal form (B48) of apolipoprotein B. Isolated cases and one important series only have been reported. We wish here to complete the description of the disease. Seven children (age 6 months to 13 years at time of diagnosis) were followed for one month to 15 years. They presented with a malabsorption syndrome, malnutrition, fatty diarrhea (steatorrhea 4-18 g/24 h), failure to thrive (height -1 to -5.5 SD for age) and sometimes disappearance of deep tendon reflexes. Biologically they had signs of malabsorption, hypocalciuria, osteoporosis, low serum iron, decreased levels of vitamins A and E, and hypo-alpha- (50-127 mg/100 ml) and beta- (73-175 mg/100 ml) lipoproteinemia due to decreased levels of plasma cholesterol (40-70 mg/100 ml), and phospholipids (34-67 mg/100 ml); apolipoproteins A1 (26-69 mg/100 ml and B (21-44 mg/100 ml) were also low. After a fatty meal, triglycerides and apolipoproteins did not increase and chylomicrons did not appear. Jejunal biopsies showed the characteristic aspect of enterocytes loaded with lipid droplets. On electron microscopy, these fat droplets were seen in the cytoplasm but neither in the endoplasmic reticulum and the Golgi complex nor in the intercellular spaces. They did not appear to be enclosed in membranes and differed from chylomicrons by their size and density. The disease could thus be due to an abnormal apolipoprotein B48, which would prevent its binding to triglycerides and thus the formation of chylomicrons.
